If it's greater than three months and it's there all the time while you're awake, that's chronic throat-clearing. Two of the most common causes of frequent throat clearing are laryngopharyngeal reflux, or LPR, and seasonal allergies, explains Song. advertisement. Reflux from the stomach, which may or may not be acidic, comes up through the esophagus and into the back of the throat, where it can irritate the voice box. People with LPR may also have post-nasal drip, an excess of throat mucus, or the feeling like something is stuck in the throat, but nothing is there.
Sometimes the mucous gathers in the back of the throat overnight, and this can be made worse by sleeping with your mouth open and breathing through your mouth instead of your nose. I wonder whether you ever have any trouble with a blocked nose, or snore or tend to breathe through your mouth a lot. This would certainly make the problem worse.
